A Pennsylvania woman recently underwent lip plastic surgery, but her lips were abnormally swollen because of an allergy to fillers.

At the time, the woman injected 1ml of filler on her lips, but after an hour her lips began to swell. She tried to use an ice pack, but the situation became worse and worse, and the swelling was seven or eight times larger than normal.

  The woman then sought the help of a doctor, who prescribed medication to ease the swelling.
